If bruising occurs, you may choose to lance a fingertip instead. If you are having difficulty obtaining blood from the forearm, call LifeScan Customer Service at 1 800
◗Under certain conditions, blood glucose test results obtained using samples taken from your forearm may differ significantly from fingertip samples.
◗The conditions in which these differences are more likely to occur are when your blood glucose is changing rapidly such as following a meal, an insulin dose, or physical exercise.
◗When blood glucose is changing rapidly, fingertip samples show these changes more quickly than forearm samples.
◗When your blood glucose is falling, testing with a fingertip sample may identify a hypoglycemic (low blood sugar) level sooner than a test with a forearm sample.
◗Use forearm samples only for testing prior to, or more than two hours after meals, insulin doses, or physical exercise.
◗Testing performed within two hours after meals, insulin doses, or physical exer- cise, or whenever you feel that your glucose levels may be changing rapidly, should be done with a fingertip sample.
◗You should also use fingertip testing whenever you have a concern about hypo- glycemia (insulin reactions) such as when driving a car, particularly if you suffer from hypoglycemic unawareness (lack of symptoms to indicate an insulin reac- tion), as forearm testing may fail to detect hypoglycemia.
What you should do:
◗Use forearm or fingertip samples for testing prior to, or more than two hours after meals, insulin doses, or physical exercise.
◗Routine testing before meals can be done either at the fingertip or the forearm.
◗Consult your healthcare professional before you begin using the forearm for testing.
